摘　　要：海南岛热带沟谷雨林物种丰富,分别在霸王岭和黎母山的5 000 m2样地调查中,发现树种703株,两地共有树种36科,其中樟科、夹竹桃科、大戟科、楝科、山矾科和桃金娘科等共有科占有的树种数量超过60%,表明两个样地相似度较高;霸王岭和黎母山沟谷雨林群落树种都以热带分布型为优,霸王岭沟谷雨林热带科成分占85.4%,热带属成分占78.5%,黎母山沟谷雨林热带科成分占88.9%,属成分占92.6%,黎母山沟谷雨林热带科属成分比霸王岭均高,反映了较强的热带性质。The tropical ravine forest of Hainan Island is rich of plant species. We investigated the plots of 5 000 m2 in Bawangling and Limushan natural reserve. 703 trees were recorded. Both areas had common species of 36 families, of which Lauraceae, Apocynaeeae, Euphorbiaceae, Meliaceae, Symplocaceae and Myrtaceae occupied over 60%, indicating that the two samples had high similarity. Trees in the tropical distribution type were dominant in Bawangling and Limushan ravine forest. In Bawangling ravine forest, the tropical components of family accounted for 85.4%, components of genus accounted for 78.5%, while in Limushan ravine forest, components of family accounted for 88.9%, components of genus accounted for 92.6%. Tropical genera components of Limushan ravine forest were higher than that of Bawangling, it meant that Limushan ravine forest had stronger tropical nature.
